Hi Gary Which version of GHC are you using? My suspicion is that ALCdevice might be a newtype falling foul of recent changes to GHC... v7.4.1: "GHC now requires, as per the standard, that if a newtype is used in an FFI declaration, then the constructor for that type must be in scope. For now you only get a warning if it is not, but in the future this will be an error."
